Good Question: Where Can I Find These Vintage Posters?

Here's reader Renata with a great find and good question on where to find vintage American agriculture posters:

I saw these in my school library and wanted prints for my kitchen. Any idea where to find them? I especially like the "Eat more corn, oats and rye" and "Food is a Weapon" prints.

Renata, what a great find! Renata sent us a website where all of these posters are displayed. We also like this one:

Here are a few good vintage poster sources. The best thing would be to just call them and tell them exactly what you're looking for. We also suggest contacting the website Fruit From Washington directly to see if they have any leads on the images they used.
